         THIS AMENDMENT is made and entered into this 12th day of September, 
   1995, by and between CONNECTICUT NATURAL GAS CORPORATION, a Connecticut
   corporation with its principal office in Hartford, Connecticut (hereinafter
   referred to as the "Company") and FLEET BANK, N.A., a bank with trust
   powers having a principal place of business in Hartford, Connecticut
   (hereinafter referred to as the "Trustee"),
    
                               W I T N E S S E T H :
    
         WHEREAS, by Agreement dated January 9, 1989 (the "Agreement"), the
   Company and The Connecticut Bank and Trust Company, N.A. entered into an
   Agreement entitled The Connecticut Natural Gas Corporation Officers
   Retirement Plan Trust Agreement; and
    
         WHEREAS, Fleet Bank, N.A. has succeeded to the trust business of The
   Connecticut Bank and Trust Company, N.A., and is currently serving as
   Trustee; and
    
         WHEREAS, the parties entered into a First Amendment to the Agreement
   dated August 5, 1993 which, among other things, renamed the Agreement; and
    
         WHEREAS, the parties entered into a Second Amendment to the Agreement
   dated February 17, 1995; and
    
         WHEREAS, the parties reserved the right to amend the Agreement in
   Article X, Section 10.1 thereof, subject to the conditions set forth
   therein; and
    
         WHEREAS, the Company wishes to amend the Agreement in the particulars
   set forth below;
    
         NOW, THEREFORE, the Company and the Trustee agree as follows:
    
         1.    The following new Section 4.4 is added to the Agreement:
    
               "4.4  Notwithstanding any other provision of this Agreement to
         the contrary, as soon as practicable following a Change of Control,
         the Company shall calculate the maximum aggregate amount required
         under the Plans to satisfy the liability to all Participants (and
         beneficiaries) who may be entitled to payments under the Plans as of
         the Change of Control and shall calculate an estimate of the expenses
         reasonably likely to be incurred by the Trust from the date of
         calculation until the termination of the Trust including the
         Trustee's fees.  Any such calculation shall be based upon the
         recommendations of an independent actuary hired by the Company
         utilizing reasonable actuarial assumptions.  The aggregate of such
         amounts for the Plans plus such additional amount as the Company
         reasonably determines to be necessary to pay the anticipated expenses
         of the Trust including the Trustee's fees is hereinafter referred to
         as the "Maximum Amount Payable".  The independent actuary shall
         promptly furnish such calculation to the Company, and the Company
         shall have the obligation to make contributions to the Trust and
         shall make contributions to the Trust in cash, within three business


         days of the receipt of such calculation, in an amount equal to the
         excess (the "Excess"), if any, of the Maximum Amount Payable over the
         then fair market value of the Trust Assets.  As of each subsequent
         valuation in accordance with Section 1.3 hereof, the independent
         actuary hired by the Company shall make a similar calculation; and if
         at any time following a Change of Control a valuation of the Trust
         Assets occurs pursuant to this Agreement, and it is determined by the
         independent actuary that an Excess shall exist, the Company shall
         within three days of notice thereof contribute in cash such amount to
         the Trust as is necessary to eliminate the Excess."
    
         2.    The following new Section 4.5 is added to the Agreement:

               "4.5  The Board of Directors of the Company and the Chief
         Executive Officer of the Company shall each have a duty to inform the
         Trustee whenever a Change of Control has occurred.  If any two
         Participants notify the Trustee in writing that a Change of Control
         has occurred, then unless the Trustee receives written notice from
         the Company that, in the opinion of independent legal counsel to the
         Company (which opinion may be based on representations of fact as
         long as counsel does not know that such representations are untrue),
         such a Change of Control has not occurred, a Change of Control will
         be deemed to have occurred for purposes of this Agreement."
    
    
         3.    Section 6.1 is amended to read as follows:
    
               "6.1  The Company shall pay any federal, state or local taxes
         on the Fund, or any part thereof, and on the income therefrom.  The
         reasonable expenses for the management and administration of the
         Trust Property, including, without limitation, reasonable expenses of
         counsel and other agents employed by the Trustee and reasonable
         compensation for its services as Trustee hereunder, may be paid by
         the Trustee from the Trust Property to the extent not paid by the
         Company.  The compensation of the Trustee shall be agreed upon from
         time to time by the Company and the Trustee in writing; provided,
         however, that if the Trustee forwards an amended fee schedule to the
         Company requesting its agreement thereto and the Company fails to
         object within thirty (30) days of its receipt, the amended fee
         schedule shall be deemed to be agreed upon by the Company and the
         Trustee."
    
         4.    The last sentence of Section 11.4 is amended to read as
   follows:
    
         "Subject, nevertheless, to the provisions of this Agreement and to
         the provisions of the Plans relating to the occurrence of a Change of
         Control, any such transaction described herein shall not suspend,
         accelerate or delay the rights of Plan Participants or the
         beneficiaries of deceased Participants to receive benefits
         hereunder."
    
         5.    The following new Article XIII is added to the Agreement:
    
                                   "ARTICLE XIII
    
               13.1  For purposes of this Agreement, a "Change of Control"
         shall mean:  (i)  the acquisition by any individual, entity or group

                                        -2-


         (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
         Exchange Act of 1934, as amended (the "Exchange Act")) (a "Person")
         of beneficial ownership (within the meaning of Rule 13d-3 promulgated
         under the Exchange Act) of 20% or more of either 1) the then
         outstanding shares of common stock of the Company (the "Outstanding
         Common Stock") or 2) the combined voting power of the then
         outstanding voting securities of the Company entitled to vote
         generally in the election of directors (the "Outstanding Voting
         Securities"); provided, however, that for purposes of this subsection
         (i), the following acquisitions shall not constitute a Change of
         Control: 1) any acquisition directly from the Company, 2) any
         acquisition by the Company, 3) any acquisition by any employee
         benefit plan (or related trust) sponsored or maintained by the
         Company or any corporation controlled by the Company or 4) any
         acquisition by any corporation pursuant to a transaction which
         complies with clauses 1), 2) and 3) of subsection (iii) of this
         Article XIII; or (ii)  Individuals who, as of the date hereof,
         constitute the board of directors of the Company (the "Incumbent
         Board") cease for any reason to constitute at least a majority of the
         board of directors of the Company (the "Board"); provided, however,
         that any individual becoming a director subsequent to the date hereof
         whose election, or nomination for election by the Company's
         shareholders, was approved by a vote of at least a majority of the
         directors then comprising the Incumbent Board shall be considered as
         though such individual were a member of the Incumbent Board, but
         excluding, for this purpose, any such individual whose initial
         assumption of office occurs as a result of an actual or threatened
         election contest with respect to the election or removal of directors
         or other actual or threatened solicitation of proxies or consents by
         or on behalf of a Person other than the Board; or (iii)  Consummation
         of a reorganization, merger or consolidation or sale or other
         disposition of all or substantially all of the assets of the Company
         (a "Business Combination"), in each case, unless, following such
         Business Combination, 1) all or substantially all of the individuals
         and entities who were the beneficial owners, respectively, of the
         Outstanding Common Stock and Outstanding Voting Securities
         immediately prior to such Business Combination beneficially own,
         directly or indirectly, more than 50% of, respectively, the then
         outstanding shares of common stock and the combined voting power of
         the then outstanding voting securities entitled to vote generally in
         the election of directors, as the case may be, of the corporation
         resulting from such Business Combination (including, without
         limitation, a corporation which as a result of such transaction owns
         the Company or all or substantially all of the Company's assets
         either directly or through one or more subsidiaries) in substantially
         the same proportions as their ownership, immediately prior to such
         Business Combination of the Outstanding Common Stock and Outstanding
         Voting Securities, as the case may be 2) no Person (excluding any
         corporation resulting from such Business Combination or any employee
         benefit plan (or related trust) of the Company or such corporation
         resulting from such Business Combination) beneficially owns, directly
         or indirectly, 20% or more of, respectively, the then outstanding
         shares of common stock of the corporation resulting from such
         Business Combination or the combined voting power of the then
         outstanding voting securities of such corporation except to the
         extent that such ownership existed prior to the Business Combination
         and 3) at least a majority of the members of the board of directors
         of the corporation resulting from such Business Combination were

                                        -3-


         members of the Incumbent Board at the time of the execution of the
         initial agreement, or of the action of the Board, providing for such
         Business Combination; or (iv)  Approval by the shareholders of the
         Company of a complete liquidation or dissolution of the Company."
    
    
         6.    Except as hereinabove modified and amended, the Agreement, as
   amended, shall remain in full force and effect.
    
         IN WITNESS WHEREOF, the parties have caused this Third amendment to
   be duly executed and the respective corporate seals to be hereunto affixed
   as of the date first above written.
